Good afternoon.

So I picked up my 535i, and I love it. There is just one small issue - I find the lumbar in the seats to be very uncomfortable and protruding. Now, I am very sensitive in the lumbar region, and I always like to minimize (or completely remove where possible) any lumbar pressure on my back.

My 535i has the four-way lumbar control. However, I honestly do not know how to use it properly. I am most comfortable when I hold the top button (or sometimes the bottom button) until I hear the hissing sound (so all of the air is decreasing from the bladder) - but I still think there is some residual air in the bladder.

Is there any way I can decrease, or remove the lumbar support? I would like the seat as concave as possible. Perhaps this might require some seat surgery...

Thanks!
